| 摘 要： | 研究了电流强度、滑动速度和载荷对Cu-Ag-Fe合金的磨损性能的影响.结果表明：由于Fe元素的时效析出强化作用,Cu-Ag-Fe合金的电磨损性能比Cu-Ag合金高出2倍多,大大提高了该合金的使用寿命.随电流强度、滑动速度和载荷的增加,合金的质量磨损率明显增加.在受电滑动条件下,磨损形式以粘着磨损,磨粒磨损和电侵蚀磨损为主,并且随着电流强度的增加,粘着磨损现象加剧.

| Abstract: | This paper studies the influences of electrical current,sliding speed and load on the sliding wear of Cu-Ag-Fe alloy.The results show that the electrical sliding wear performance of Cu-Ag-Fe alloy increases more than 2 times than that of Cu-Ag alloy due to the aging strengthening action of Fe element,which greatly lengthens the service life of Cu-Ag-Fe alloy.With the increase of electrical current,sliding speed and load,the mass wear rate of Cu-Ag-Fe alloy dramatically increases.During the electrical sliding processes,the adhesive wear,abrasive wear and electrical erosion are the dominant mechanisms.The phenomena of the adhesive wear intensify with the adding electrical current. |
